nRF9160dk FOTA using external flash, ncs 2.0.2

Hi, 

I am using nRf9160dk with mcuboot secondary image on external flash base on AZURE_FOTA example, ncs 2.0.2.

Found the bootloader cannot runs primary image.

So, I need advice on how to set up the mcuboot secondary with SPI flash.

*** Booting Zephyr OS build v3.0.99-ncs1-1  ***
I: Starting bootloader
W: Failed reading sectors; BOOT_MAX_IMG_SECTORS=128 - too small?
E: Image in the primary slot is not valid!
E: Unable to find bootable image

Checked the partition with west build -t partition_manager_report .

  • Hi,

     

    child_image\mcuboot\prj_mcuboot.conf

    You have two choices wrt. configuring a child_image:

    child_image/$image.conf

    This overrides the original default configuration for the child_image.

    Or:

    Replace the default configuration by setting:

    child_image/$image/prj.conf

     

    This approach will not use the default configuration for the image, and will require larger configuration files (ie. def_config + your wanted local configs)

     

    I would recommend that you move this file to:

    child_image\mcuboot.conf

     

    child_image\mcuboot\boards\nrf9160dk_nrf9160_mcuboot.overlay

    This should be child_image\mcuboot\boards\nrf9160dk_nrf9160.overlay

     

    The algorithm here must follow the following rule:

    child_image/$image/boards/$BOARD

     

    Note that mcuboot runs in secure, so it will be "nrf9160dk_nrf9160" that is the board chosen for this child image.

     

    pm_static.yml

    You have overlapping sections in this file:

    external_flash:
      address: 0x0
      device: mx25r6435f
      region: external_flash
      size: 0x800000 
    mcuboot_secondary:
      address: 0x0
      device: mx25r6435f
      region: external_flash
      size: 0x70000

     

    You should define "external_flash" with a start address after the end_addr of mcuboot_secondary.

     

    Since you've already setup the corresponding "nordic,pm-ext-flash" section in device-tree, you can remove (or move the pm_static.yml to a backed up location) and rely on the generated build\partitions.yml file instead.

     

    Kind regards,

    Håkon

  • Hi,

    My code is struck in an infinite loop when booting the mcuboot_primary slot.

    I am taking your advice and doing:

    I would recommend that you move this file to:

    child_image\mcuboot.conf

    Rounding the mcuboot.conf as your recommend.

    This should be child_image\mcuboot\boards\nrf9160dk_nrf9160.overlay

    This suggestion has also been implemented in my project.

    Since you've already setup the corresponding "nordic,pm-ext-flash" section in device-tree, you can remove (or move the pm_static.yml to a backed up location) and rely on the generated build\partitions.yml file instead.

    Remove pm_static.yml since I have define "nordic.pm-ext-flash"

    Could you provide me some advice and confirm my configuration from my initial post is the root cause of the issue?

  • Hi,

    Try commenting out this line in child_image/mcuboot.conf:

    CONFIG_DEBUG_OPTIMIZATIONS=y

    Build can run without error, but I got a forever loop error after flash the firmware to the board.

    Wandering the return data indicates that the device id does not match because [00 00 00].

    By the way, I already confirm the device id [c2 28 17] is can use or not.

    I have been tested with the spi_flash example, it can read/write in normally with the device id [c2 28 17].

    Then change the device to [00 00 00] in overlay file.

    Program runs as normally, can connect to the azure IoT hub and can start to do FOTA task.

    Please assist me in solving this issue.

    Again, my propose is update firmware via FOTA using external flash with the ncs 2.0.2 or newer version.

    Since the TF-M is still trying to solve the problem, I agree to work with the SPM.

    By the way, please let me know if there are any TF-M updates.

    Appreciate your help.

  • Hi,

    By the way, I already confirm the device id [c2 28 17] is can use or not.

    I have been tested with the spi_flash example, it can read/write in normally with the device id [c2 28 17].

    Then change the device to [00 00 00] in overlay file.

    This is the jedec id for your external flash, which can be read out from the datasheet of your used external flash.

    For the MX25R64 mounted on the nRF9160-DK, it is c2 28 17, and if you read all zeros, then it has issues connecting to your flash.

    For the nRF9160-DK, you must switch in the pins for communicating with the flash, as explained in this post:

     RE: Full modem update configuration 

     

    Note that this is for the board controller, ie. nrf9160dk_nrf52840, so it is important that you set the switch into "NRF52" position before programming the above snippet.

     

    Kind regards,

    Håkon

  • Hi  

    I want to know if the TFM issue has been resolved.

    If so, could you describe how to use it?

  • Hi,

     

    Yes, this issue was resolved with this PR:

    https://github.com/nrfconnect/sdk-nrf/pull/8363

    It is present in ncs v2.1.0.

     

    Rung said:

    Based on your previously used project, you take away the SPM config:

    CONFIG_BUILD_WITH_TFM=y
    # CONFIG_SPM=n

     

    Could you try this and see if this works as expected?

     

    Kind regards,

    Håkon

  • Hi   I'm having a similar problem, for the last couple of weeks. 

    NCS 2.1.0

    I'm using the HTTP application update, and it works OK when using FOTA and internal flash however it doesn't work when using external flash. 

    I get an error

  • Hi   I'm having a similar problem, for the last couple of weeks. 

    NCS 2.1.0

    I'm using the HTTP application update, and it works OK when using FOTA and internal flash however it doesn't work when using external flash. 

    I get an error 

    Failed reading sectors; BOOT_MAX_IMG_SECTORS=256 - too small?
    Cannot upgrade: not a compatible amount of sectors

  • Hi  and  

     

    My deepest apologies for the inconvenience.

    Unfortunately, there is another breaking change in NCS v2.1.0, that blocks for using SPI based flash ("spi_nor") in mcuboot.

    You will need in total 2 changes:

    1. in your child_image/mcuboot.conf, you will need to add this symbol when using SPI and flash:

    CONFIG_PM_OVERRIDE_EXTERNAL_DRIVER_CHECK=y

     

    2. In addition, there is a bug with the flash_device that mcuboot picks up through the "partition manager" script system.

    This line in ncs_v2.1.0/nrf/cmake/partition_manager.cmake:

    https://github.com/nrfconnect/sdk-nrf/blob/v2.1.2/cmake/partition_manager.cmake#L215

     

    Shall be changed to:

        DEVICE "DT_CHOSEN(nordic_pm_ext_flash)"

     

    The second point is handled in this PR, but due to release-note changes as well, it is not easy to cherry pick directly:

    https://github.com/nrfconnect/sdk-nrf/pull/9169

     

    Could you try these two steps and report back if this helps the scenario?

     

    Kind regards,

    Håkon

  • Oh my goodness..... IT WORKS

    Thanks so much for the support.

  • Hi Marshall,

     

    I'm glad to hear that it is working at your end now.

    I'll pursue this issue internally, and make sure it is handled.

     

    Kind regards,

  • Hi ,

    Thanks for your support and sorry for my late reply.

    I works properly with the example.

    By the way, my external flash needs to be portioned.

    I created a static partition for the external flash using the "pm static.yml" file.

    Can we do the FOTA utilizing the external flash static partition?

  • Hi,

    Rung said:

    Ok, good, so that means that you have implemented the formerly mentioned fix for ncs v2.1.0.

     

    Which image are you downloading?

    When updating, it is important that the original static partition is kept for all update-images as well, to ensure that mcuboot recognizes the image properly.

     

    Kind regards,

    Håkon
